To allwizom it may concern: a I form part of the longitudinally extending Be it known that I, FRANK M. JosLIN, a partitlon 13, half of the bottom, an extra citizen of the United States, residing at Amside and a part of the top closure. The sterdam, Montgomery county, State of New other section 19 of similar size and shape 1 York, have invented certain new and useful forms with the section 18 the partition 13, 60 Improvements in Collapsible Cartons, of also the other half of the bottom, a second i which the following is a specification. additional side on the opposite side from The invention relates to collapsible carthe first, and the remaining part of the top tons, and more especially to such cartons closure.

The carton comprises the usual longitudi- It will be seen that the sections 18., 19 nal side walls 10, the transverse side walls thus together form a top closure and also 11, the transverse partitions 12, and a longiself-contained means to lock the closure in 815 tudinally extending partition 13.

By having the locking means no self-contained in the single blank, a very positive lock is provided and the stresses induced thereby are localized in the said blank. Furthermore, the arrangement is such that the parts can be manufactured very cheaply.

While a carton having two tabs 20 and corresponding tongues has been described,

it is. obvious that the number of tabs and tongues used will depend on the size of the carton or box, and any number desired may be used. Furthermore, although a carton having twelve cells has been illustrated, the

number of cells is not material, as the in vention is applicable to cartons having two or more cells.

Having thus described the invention, what I is claimed anddesired to be secured by Letters Patent is:

1. A collapsible carton or box having front and rear side walls, a partition parallel to said walls, a top closure, a bottom, two additional side. walls outside of the first mentioned walls, the said bottom, additional through the slot, said tab formed with a slot to receive the tongue.

3. A collapsible carton or box having a top closure consisting of two overlapping parts, one part formed with a slot and the other a tongue, a partition having a tab adapted to extend through said slot and said tab having a slot adapted to receive said tongue.

4:. As an article of manufacture, a blank comprising two substantially equal sized sections connected by a tab formed with two spaced slots, one section at the edge opposite the said tab having a tongue adapted to enter said slots, the other section adjacent the edge opposite the said tab formed with a slot adapted to receive the tab.

5. A collapsible carton or box having a partition, bottom, side Walls and top formed from a single blank, a tab on said partition and a tongue on the top interlocking with said tab to secure the top in closed position.

6. A collapsible carton or box having a top consisting of two sections, each hinged to the topof a side wall, a partition having a tab formed with a slot, the top sections having registering slots adapted to receive the tab and one section having a tongue adapted to extend through the slot in the ta In testimony whereof I affi-x my signature.
